Am experiencing a similar issue which may be the same bug. OS: Ubuntu 20.04 Kernel: 5.15.0-86-generic Desktop: GNOME Graphics: AMD
Just before/after logging in, the screen flickers and/or goes blank. Attempting to switch to a terminal using Ctrl+Alt+F-keys doesn't help. Attempting to restart using Ctrl+Alt+Del doesn't work. Choosing the previous kernel (5.15.0-84-generic) from the GRUB menu instead, when booting, avoids the issue.

I use the cinnamon desktop. After I type in the user password at the display- manager to login, the desktop shows for 1 second and then the screen goes blank. I solved the problem through switching the desktop to cinnamon (software rendering) at the display-manager and then installed 6.2.0-34-generic instead of 5.15.0-86 to be able to use the normal cinnamon desktop again.
